My ex-best friend is a bitch <3

Hi!!! Today I'm going to tell you a story about why I have very few friends these days.

Well, in July last year, I started to like my best friend. She was bisexual, so it was fine for me to like her. I tried to get closer to her and give her some signals. I'd compliment her and lie on her shoulder sometimes. And then one day I ended up telling her. She didn't know how to react and I got nervous. It was awful. I started crying and apologizing to smooth things over. But then she ended up saying that maybe she could make things work and called me over to her house to watch movies and eat cookies. Nothing ended up happening apart from the movies and cookies btw. And we ended up pursuing our friendship as normal, but after a few months I realized that she was pulling away from me. I felt sad and blamed myself for it, but since she would talk to me normally again afterwards, I didn't really care. Well, in May of this year, she started hanging out with another "friend" of mine. This friend had spoken badly about me in 2022, but I ended up forgiving her (I shouldn't have done that). She also knew that I liked my ex-best friend, and she spent three months giving me tips on how to win her over. Yes, she gave me tips on how to date the girl she would me dating in some months. Later, they became closer than ever and distanced themselves from me. My other friends also distanced themselves. And on Valentine's Day (July 14 in my country), one of them sent a letter to the other. I had already understood what was going on, but I wanted my ex-best friend to be mature enough to separate her new relationship from our friendship. So I asked her why she was pulling away from me and if it was because of her new girlfriend. She said she really wanted to keep talking to me, but then said she'd been trying to get away since I said I liked her. We had a fight and I blocked her and her girlfriend on all social networks. Unfortunately, the three of us study in the same classroom, so it's inevitable to see them cuddling next to me (yes, they sit next to me and cuddle together in class. What's worse is that my ex-best friend stares at me all the time. As if I'm trying to see how I react ??). Now that school is back in session, it's much better for me to live in the school environment, since I spent a month with almost no contact with the two of them. And now my ex-best friend's girlfriend hasn't gone back to school. And they've already started two weeks ago. I don't know why and I don't want to ask anyone. But it's very nice not to see her. She's a horrible person. He gave my ex-best friend cigarettes and he's sure to hurt her. I don't want to be the one to say "I told you so", but I know that everything is going to go wrong for them. And I hope that when it does, my ex-best friend doesn't want to come back crying to me.
